Deep learning classification

Since deep learning is all the rage, and I'm curious and want to learn, I've been thinking of a few applications of deep learning to quantified self data.

- Analyze audio logs to classify who speaks when
- If you record everything you say, it would be interesting to see how much time you spend talking vs listening and with whom.
- Done by that video conferencing service that has ads on Masters of Scale
- Might be a solved problem?
- How to gather trainingdata?
- Classify activity into categories
- Training data could be RescueTime exports
